Overview of Changes in audiowmark-0.6.5:
* improve robustness for low quality material
- robust sync score peak selection using local mean
- use lower sync threshold (introduce --sync-threshold option)
- always decode n best matches (introduce --n-best option)
- distance based AB pattern merging
- distance based ALL pattern merging
- change output order: print most relevant matches first
- deprecate short payload
* fix speed detection result output for default key
* ship more m4 macros to fix automake on some target systems
Overview of Changes in audiowmark-0.6.4:
* reduce memory usage:
- for speed detection, especially when using multiple keys
- for resampling of input files with sample rate != 44100
- split long input files into smaller chunks (get --chunk-size option)
* optimize performance for speed detection / normal sync
* improve detection for libgcrypt, use pkg-config if available (#72)
* fix problems in make check (#72)
Overview of Changes in audiowmark-0.6.3:
* update HLS support to build with ffmpeg-7 API (#68)
* preserve wav subformat (#64)
- write float/double wav output for wav float/double input
- write signed 16, 24 and 32 bit wav output for 16, 24, 32 bit wav input
- added test that wav subformat format is preserved (make check)
* improved RawConverter:
- support float/double input/output (very fast on little endian systems)
- fix bug for unsigned integer raw input/output (16, 24 and 32 bit)
- better tests (make check)
- faster 16/32 bit conversion on little endian systems
* add format wav-pipe for very long input/output streams on stdin/stdout
* performance optimizations for SFOutputStream
* add documentation for Windows/Cygwin builds (#45)
Overview of Changes in audiowmark-0.6.2:
* improved robustness of the watermark detection a lot for many cases
* improved handling if more than one key needs to be used for detection
- support using --key multiple times for audiowmark get
- support naming watermark keys (key name defaults to filename)
- extend JSON and regular output to report key name for matches
* merge architecture documentation for developers written by Tim Janik (#49)
* support RF64 output (--output-format rf64) for huge wav files (#30, #2)
* use hann window function to improve robustness/quality for some files (#48)
* fix building against zita-resampler installed in non-standard location (#39)
* replace sprintf with string_printf: sprintf is deprecated on macOS (#33)
* fix build errors related to PRNG on new clang compilers (#29)
* fix problems in videowmark due to command line option ordering (#23)
Overview of Changes in audiowmark-0.6.1:
* improve speed detection/correction
- performance optimizations to make --detect-speed faster
- improve accuracy of speed detection
- make it work properly with short payload
- add second, slower / more accurate algorithm (--detect-speed-patient)
* fix segfaults during hls-prepare (#11)
* read all input if a process provides audio on stdin to avoid SIGPIPE (#19)
* improve infrastructure for testing audiowmark
- run some scripts for 'make check' to ensure everything works correctly
- add CI which builds/tests audiowmark automatically using github actions
- support various sanitizer builds / STL C++ debug builds
- fix some issues triggered by sanitizers
* add --strict option: provide strict and more permissive mode
- "input frames != output frames" is only an error if --strict is used
- enforce payload size if --strict is used
* improve command line parsing error messages
* documentation updates
* minor fixes
Overview of Changes in audiowmark-0.6.0:
* implement speed detection/correction (--detect-speed)
* Add '--json' CLI option for machine readable results.
Overview of Changes in audiowmark-0.5.0:
* support HTTP Live Streaming for audio/video streaming
* fix floating point wav input
* improve command line option handling (ArgParser)
* support seeking on internal watermark state
Overview of Changes in audiowmark-0.4.2:
* compile fixes for g++-9 and clang++-10
* add experimental support for short payload
Overview of Changes in audiowmark-0.4.1:
* initial public release
Overview of Changes in audiowmark-0.4.0:
* add initial video watermarking support (videowmark)
Overview of Changes in audiowmark-0.3.0:
* replace padding at start with a partial B block
* add algorithm for decoding the watermark from short clips
Overview of Changes in audiowmark-0.2.1:
* add limiter to avoid clipping during watermark generation
Overview of Changes in audiowmark-0.2.0:
* support input/output streams
* support raw streams
* some performance optimizations
* unified logging and --quiet option
* improved mp3 detection to avoid false positives
* split up watermarking source (wmadd/wmget/wmcommon)
Overview of Changes in audiowmark-0.1.0:
* initial release
